Read following as embodiment and the description provided in a non-limiting manner on the basis of reference accompanying drawing, the present invention will be understood better, and other feature and advantage more clearly will manifest, wherein:
-Fig. 1 is the schematic diagram according to power drive system of the present invention, and described power drive system is implemented according to control method of the present invention;
-Fig. 2 illustrates three views of the axial cross section of the hydraulic accumulator of described power drive system, and it comprises three fill levels A, B and C successively;

Detailed description of the invention
Fig. 1 illustrates the power drive system 1 of vehicle, and described power drive system comprises combustion engine 2, described internal combustion engine drive variable-displacement pump 4.Variable-displacement pump 4 is by hydraulic fluid pumping from tank body 6, so that stuffing pressure energy storage 8.
Pressure energy accumulator 8 has the flexible membrane 12 air under pressure 10 be separated, and described air under pressure comprises the nitrogen from fluid usually, the pressure that the pressure durations of described nitrogen remains described gas be roughly equal to.
Compression fluid is subsequently by using as motor operated variable-displacement hydraulic compressor 20, and described hydraulic compressor is connected to differentiator 22, and described hydraulic compressor drives two drive wheels 24 of the given vehicle bridge of vehicle, so as between these to be taken turns distributed power.In contrast, during the braking of vehicle, drive wheel 24 can drive as pump operated hydraulic compressor 20, so as to refill Pressure energy accumulator 8 and thus so that in the deboost phase or at descending time reclaim the kinetic energy of vehicle.
In order to the running of optimization combustion engine 2, especially in order to reduce the number of times of described engine starting, and in order to provide high power during its operation, technical personnel makes every effort to stored energies a large amount of as far as possible make every effort to use energy a large amount of as far as possible in single in Pressure energy accumulator 8.
It should be noted that when electronic power plant substitutes combustion engine, the frequency reducing the startup of described power plant can also being realized, especially in order to reduce the number of times of the startup causing current draw peak value.
Fig. 2 illustrates hydraulic accumulator 8, and under the first situation A, described hydraulic accumulator is emptied completely, and hydraulic pressure circuit is such as opened and is directly placed in and is connected with tank body 6.
In this case, gas 10 farthest expands, and film 12 declines until contact with bottom retainer 14, and described bottom retainer limits described film does not allow its expansion surmount.The internal pressure of gas 10 then becomes residual pressure P0, and its maximum volume V0 represents the nitrogen capacity of described energy storage 8.
Under the second situation B, Pressure energy accumulator 8 is filled a little by the pressure of fluid, and film 12 is in its underpart operating position, and described bottom operating position provides the minimum pressure threshold P1 of the gas 10 and maximum operational volume V1 of described gas.
The bottom operating position of film 12 continues acceptable extreme lower position when the risk not having film to decompose, to ensure the reliability of energy storage 8.Therefore, the minimum operational pressure of hydraulic circuit is substantially equal to P1.
Under the third situation C, Pressure energy accumulator 8 is filled by the pressure altitude of fluid, and film 12 is in its highest operating position, and the highest described operating position provides the minimum volume V2 of maximum pressure P2 in gas 10 and described gas.
Gas 10 subsequently between described two volumes, be namely subject to the impact of volume differences Δ V between maximum volume V1 and minimum volume V2, described volume differences and corresponding pressure are multiplied the stored energy representing and can be resumed.
In fact, the pressure of gas 10 should swing in the following manner between its minimum value P1 and its maxim P2, namely in the conceived case, another limit is gone to from a limit, to store and to use energy a large amount of as far as possible subsequently in single during the circulation refilling and the discharge running of Pressure energy accumulator 8.
The chart of Fig. 3 at an upper portion thereof shown in as the change 30 of the gaseous tension P in the Pressure energy accumulator 8 of the function of time t, and the startup of combustion engine 2 is shown in its underpart, mark A be stop and D for starting.
When energy storage 8 is initially filled to its maximum pressure P2, described energy storage is normally discharged during the vehicle driving to the hydraulic compressor 20 by using as pump provides power.Combustion engine is in stop A place.
For management implementation according to the pressure P in the computing machine of the power drive system 1 of control method of the present invention both gaging pressure energy storage 8, measure again its pressure over time, i.e. rate of discharge dP/dt, described rate of discharge is connected with the use of fluid by the hydraulic compressor 20 causing described fluid and flow.
Should be noted that, fluid flow especially as following variable function and change, that is, the moment of torsion on the regulated quantity of the pressure P in energy storage 8, the discharge capacity of hydraulic compressor 20, the speed of vehicle, the required drive wheel of chaufeur and the opposing moment of torsion caused due to operation conditions.Supervisory computer must continue the rate of discharge dP/dt checking energy storage 8, and described rate of discharge can change.
When time t0, slight pressure as P1 ' is greater than P1, by the current rate of discharge dP/dt of energy storage 8, described control method detects that its pressure arrives minimum threshold P1 by during the time t1 corresponding in the end of the startup D with combustion engine 2, pump 4 starts to perform refilling of energy storage.Time difference Δ t between time t0 and t1 is corresponding with the time started needed for described combustion engine 2.
From the time t1 that pressure has dropped to minimum pressure threshold P1, pressure raises again, and most promotion is to maximum pressure P2, and described maximum pressure and combustion engine are by corresponding for the time t2 being again in stop A place.
For next circulation, the discharge of Pressure energy accumulator 8 can be started by the same time difference Δ t between time t3 and t4 subsequently again, but the wherein beginning of time t3 and the pressure P 1 being greater than P1 ' " corresponding; because in this case; before pressure is greater than relative to the decline dP/dt of time, hydraulic compressor 20 consumes more fluid flow.
The block diagram of Fig. 4 shows the component implemented according to control method of the present invention.
Calculate pressure P that component 42 records according to continuing in energy storage 8 and calculate according to record minimum threshold pressure P1 in memory the horizontal E of useful capacity be included in described energy storage.
Compared with horizontal for useful capacity in energy storage 8 E is consumed with the power P of the expression ENERGY E real-time change consumed by hydraulic compressor 20 in the described time by comparator 44 subsequently, to determine actuating pressure P1 ', described actuating pressure will trigger the startup of combustion engine 2.Count consumed power P to consume, thus guarantee the time difference Δ t that defers to needed for starting apparatus combustion engine 2, the time difference is recorded in memory.
The optimization of the running of power drive system 1 thus realize in simple, reliable and actv. mode.In addition, by control method being integrated in the supervisory computer for power drive system 1, and by using existing sensor, in particular for measuring the sensor of the pressure of fluid, described control method can be performed economically.
As modification, similar control method can be used for managing the startup of combustion engine 2, to refill multiple Pressure energy accumulators in parallel.
